Category Description
A GSM intercom uses a SIM card to make a call over over the mobile network when you have a Visitor. This ensures your intercom calls are always answered as multiple numbers can be set. This also gives the impression to the Visitor that someone is inside the property when in fact there may not be. This is a security advantage over ALL other intercom systems.
